  • Patent number: 8848654
    Abstract: A first pilot signal is transmitted at a first frequency for a first coverage area (e.g., an outdoor area). A second pilot signal is transmitted at a second frequency for a second coverage area (e.g., an indoor area). The first pilot signal at the second frequency is transmitted into a portion of the second coverage area, the second coverage area at least overlapping with the first coverage area. Further, the first pilot signal is transmitted at the second frequency in the second coverage area. In an example, the first pilot signal at the first frequency is transmitted from an outdoor base station, the second pilot signal at the second frequency is transmitted by an indoor base station, the first pilot signal at the second frequency is transmitted into the second coverage area (e.g., an interior of a building from a building exit point) by an antenna (e.g., not necessarily at a base station) and the second pilot signal at the first frequency is transmitted by the indoor base station.

  • Patent number: 8346259
    Abstract: The invention provides a method for hand-over of a terminal from a first base station to a second base station, radio network element, terminal, base station and a communication system. The method for hand-over of a terminal from a first base station to a second base station, wherein said first base station is EV-DO enabled in an access network and said second base station is not EV-DO enabled, said method comprising: transmitting an EV-DO pilot signal from said second base station to said terminal; sending a route update message including an EV-DO pilot strength from said terminal if said EV-DO pilot strength is above a predetermined threshold; calculating a CDMA pilot strength based on said EV-DO pilot strength; and performing the hand-over of said terminal to said second base station when CDMA pilot strength is above the hand-over threshold.

A second pilot signal is transmitted at a second frequency for a second coverage area (e.g., an indoor area). The first pilot signal at the second frequency is transmitted into a portion of the second coverage area, the second coverage area at least overlapping with the first coverage area. Further, the first pilot signal is transmitted at the second frequency in the second coverage area. In an example, the first pilot signal at the first frequency is transmitted from an outdoor base station, the second pilot signal at the second frequency is transmitted by an indoor base station, the first pilot signal at the second frequency is transmitted into the second coverage area (e.g., an interior of a building from a building exit point) by an antenna (e.g., not necessarily at a base station) and the second pilot signal at the first frequency is transmitted by the indoor base station.
